Do mothers of overweight Argentinean preschool children perceive them as such?

Childhood overweight is rapidly on the rise and underlies the younger presentation of diabetes. The aim of this study was to determine the association between overweight and age, sex, and the perception of the overweight children by their mothers. Three hundred and twenty-one (160 males) children (mean age 4.39 +/- SD 0.83 yr) [body mass index (BMI) 16.6 +/- 2.11] from schools at the kindergarten level were evaluated. Data on age, sex, weight, and height were recorded. At risk for overweight and overweight were defined as a BMI of > or = 85th or > or = 95th percentile, respectively. Written questionnaires for mothers' perceptions about their children's eating habits (a lot, right, little, or very little) and shape (very fat, fat, normal, and thin) were performed. The prevalence of at risk of overweight and overweight was 19 and 18.4%, respectively. There was a significant difference in the proportion of distorted perception of shape between mothers of normal-weight children vs. those of at risk of overweight and overweight children (17 vs. 87.5%, p < 0.001). Seventy-six and 98% of mothers of overweight and at risk of overweight children, respectively, rated them as normal or thin. Mothers exhibited poor overall ability to estimate the way at risk of overweight and overweight children ate. There was a significant difference in the proportion of distorted perception of eating habits between mothers of normal-weight children vs. those of at risk of overweight and overweight children (36.3 vs. 90.8%, p < 0.001). Eighty-four and 96% of mothers of obese and overweight children, respectively, thought that their children ate right or little. A multiple regression analysis using BMI > 95th percentile as the dependent variable showed that the mothers' perceptions of shape and eating habits [odds ratio 4.5; 95% confidence interval (CI) 2.5-7.8; p < 0.0001] were both significant independent risk factors for overweight, adjusted for age and sex. The agreement between the perception of shape and eating habits vs. the medical records BMI > 95th percentile was poor; for shape: kappa 0.31 + 0.07; 95% CI 0.17-0.44, and for nutrition: 0.14 + 0.06; 95% CI 0.02-0.27. This suggests that the mothers' perceptions of shape and eating behavior is a predictor of obesity and could be used in clinical practice as a simple tool to identify children at high risk for overweight.     

Minority mothers' perceptions of children's body size.

OBJECTIVE: To investigate African-American and Hispanic mothers' perceptions of their children's body size using a scale with child figure silhouettes and compare those perceptions with their children's actual body mass index. METHODS: A set of child figure silhouettes was developed depicting 4 and 5 year-old African-American and Hispanic children. Body mass index was systematically estimated for each child figure on the set of silhouettes. Minority mothers with children enrolled in ten Head Start centers (n=192) were interviewed using the silhouettes, and height and weight measurements were taken on their children. Head Start, a comprehensive child development program that serves children aged 3 to 5 years old, was chosen because of the large percentage of minorities, the low-income status of the families, and the age of the children. RESULTS: Significant differences were found between mothers' perceptions of their children's body size and the actual body size of the children. On average, mothers perceived their children to be thinner than their actual size. Furthermore, of those mothers with children at risk for overweight or overweight, two-thirds were either satisfied with their children's existing body size or wanted their children to be heavier. However, half of the mothers of children above the 95th percentile for BMI wanted their children to be thinner. CONCLUSIONS: These data suggest that minority mothers' perceptions of their children's body size may not be consistently biased in one direction. Despite the possible social norm for a larger body size among low-income minorities, some mothers of overweight minority children do perceive their children to be too heavy when they reach a certain size.     

Hypercholesterolemia in Thai primary school children: Relation to maternal and nutritional factors

Background: There is evidence to show that atherosclerosis can occur in young children and that elevated total cholesterol and low density lipoprotein cholesterol concentrations are risk factors for atherosclerosis. The aim of the present cross-sectional study was to investigate the influence of maternal and nutritional factors on blood cholesterol in primary school children.
Methods: One hundred and ninety-five population-based mother–child pairs (obese child–overweight mother pairs, n = 60; obese child–normal-weight mother pairs, n = 48; wasted child–overweight mother pairs, n = 37; normal-weight child–normal-weight mother pairs, n = 50), were enrolled in the study. Various anthropometric parameters were measured and serum lipids of subjects were further determined. Biological data and children's eating behavior were obtained from the mothers through interviews.
Results: Hypercholesterolemia was found in 64.6–65% of obese children, 24.3% of wasted children and in 56% of the normal-weight children; whereas the proportion of children in all groups who had normal blood cholesterol levels was in the lower range. Multivariate logistic regression indicated that mother's serum cholesterol (odds ratio [OR], 2.41; 95% confidence interval [CI]: 1.12–4.78), child obesity defined by weight-for-height Z-score > +2SD (OR, 2.56; 95%CI: 1.33–4.98), and child's energy intake ≥75th percentile (OR, 2.59; 95%CI: 1.01–6.66) were the significant factors associated with hypercholesterolemia in children.
Conclusion: Hypercholesterolemia in school children is associated with familial factor, bodyweight and nutrient intake. Elevated blood cholesterol was also found in some of the normal-weight and wasted children. Effective family-based intervention programs are urgently needed to modify risk factors predisposing to coronary heart disease.     

Decreased quality of life associated with obesity in school-aged children

OBJECTIVES: To examine the association between health-related quality of life and body mass index (BMI) in preadolescent school-aged children and to provide the possible risk factors among participant characteristics, BMI status, and health-related quality of life.Design, Setting, and PARTICIPANTS: Cross-sectional analysis of 371 (50% female; 32% minority) children from a community-based sample of 8- to 11-year-olds participating in an ongoing cohort study, excluding those who had sleep apnea or who were born prematurely. Using BMI percentiles for age and sex, 17.5% of the children were considered overweight (BMI > or =95th percentile), 12.4% were at risk for overweight (BMI 85th-94th percentile), 8.1% were relatively underweight (BMI <20th percentile), and the remaining 62.0% were of normal weight (BMI 20th-84th percentile). MAIN OUTCOME MEASURES: Health-related quality-of-life scores as determined by the Child Health Questionnaire-Parent Form 50, dichotomized into the bottom quartile or decile. RESULTS: After adjustment for covariates (host factors and health status measurements), overweight children compared with normal weight children scored lower on the Psychosocial Health Summary (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.1-3.6) and on subscales measuring self-esteem (OR, 3.5; 95% CI, 1.9-6.3), physical functioning (OR, 2.8; 95% CI, 1.7-6.8), and effect on the parent's emotional well-being (OR, 2.0; 95% CI, 1.1-3.6). Compared with the normal weight group, children who are at risk for overweight scored significantly lower for physical functioning. CONCLUSION: Overweight children have an increased odds of low scores for several health-related quality-of-life domains, suggesting the importance in considering such dimensions in programs aimed at further understanding obesity in children.     

Family history and parental recognition of overweight in Croatian children

The aim of this study was to evaluate the perception of parents on the weight status of their offspring, particularly in relation to a family history of obesity and obesity-related illnesses. A cross-sectional study of 1,068 child-parent dyads sampled at school entry health examination was conducted (median age of the child 6.75 years, range 5.7-8.3 years, 50.3 % males). The parental perception of the weight status of their child was compared to the body mass index (BMI, kilogram per square meter), calculated from measured weight and height. Weight status (underweight, normal, overweight, and obese) was defined using the United States Centers for Disease Control and Prevention BMI for age reference charts. Backward multiple linear regression analysis was used to determine possible predictors of parental misclassification of overweight/obese children. Among this cohort of children, 12 % were overweight, 10.2 % obese, and 8.1 % were underweight. Only 24.8 % of obese children and 2.2 % of overweight children were considered "overweight" by their parents. A positive family history was not significantly associated with parental recognition of overweight. Parental misperception of overweight/obese children as being normal was related to the child BMI z-score (odds ratio (OR) 0.036; 0.012-0.111) and diabetes in family history (OR 3.187; 1.207-8.413). CONCLUSION: The majority of parents did not perceive their overweight/obese children as overweight. As having an obese family member or one who has suffered from an obesity-related illness does not increase the parental ability to recognize overweight in their children, strategies to increase public awareness about the importance of one's family medical history are needed.     

Obesity and associated modifiable environmental factors in Iranian adolescents: Isfahan Healthy Heart Program − Heart Health Promotion from Childhood

OBJECTIVE: To evaluate the prevalence of overweight and obesity among Iranian adolescents and their relationship with modifiable environmental factors. METHODS: The subjects of the present study were 1000 girls and 1000 boys, aged between 11 and 18 years selected by multistage random sampling, their parents (n = 2000) and their school staff (n = 500 subjects) in urban and rural areas of two provinces in Iran. Data concerning body mass index (BMI), nutrition and the physical activity of the subjects were analyzed by SPSSV10/Win software. RESULTS: The prevalence of 85th percentile 95th percentile in girls was significantly higher than boys (10.7 +/- 1.1 and 2.9 +/- 0.1%vs 7.4 +/- 0.9 and 1.9 +/- 0.1%, respectively; P < 0.05). The mean BMI value was significantly different between urban and rural areas (25.4 +/- 5.2 vs 23.2 +/- 7.1 kg/m2, respectively; P < 0.05). A BMI> 85th percentile was more prevalent in families with an average income than in high-income families (9.3 +/- 1.7 vs 7.2 +/- 1.4%, respectively; P < 0.05) and in those with lower-educated mothers (9.2 +/- 2.1 vs 11.5 +/- 2.4 years of mothers education, respectively). The mean total energy intake was not different between overweight or obese and normal-weight subjects (1825 +/- 90 vs 1815 +/- 85 kCal, respectively; P > 0.05), but the percentage of energy derived from carbo-hydrates was significantly higher in the former group compared with the latter (69.4 vs 63.2%, respectively; P < 0.05). Regular extracurricular sports activities were significantly lower and the time spent watching tele-vision was significantly higher in overweight or obese than non-obese subjects (time spent watching telelvision: 300 +/- 20 vs 240 +/- 30 min/day, P < 0.05). A significant linear association was shown between the frequency of consumption of rice, bread, pasta, fast foods and fat/salty snacks and BMI (beta = 0.05-0.06; P < 0.05). A significant correlation was shown between BMI percentiles and serum triglyceride, high-density lipoprotein-cholesterol and systolic blood pressure (Pearson's r = 0.38, -0.32 and 0.47, respectively). CONCLUSIONS: Enhanced efforts to prevent and control overweight from childhood is a critical national priority, even in developing countries. To be successful, social, cultural and economic influences should be considered.     

Risk factors for overweight in 2- to 6-year-old children in Beijing, China.

OBJECTIVE: To assess the prevalence of overweight among Chinese preschool children and to explore risk factors of childhood obesity focusing on parental characteristics, feeding practice and lifestyle. METHODS: Data on 930 families with 2- to 6-year-old children in five kindergartens were obtained in a cross sectional study. Families were randomly selected from two of all six urban districts in Beijing, China. Information on parental characteristics, dietary habits, lifestyle habits, and feeding practice was collected by parental self-report questionnaires. The children's stature and weight were measured in light clothing and without shoes. Overweight and obesity were defined according to international cut-off values, as proposed by the International Obesity Task Force. Multivariate regression analysis was used to explore risk factors of child overweight. RESULTS: The overall prevalence of overweight and obesity was 10.7% and 4.2%, respectively, and increased with age. The prevalence of child overweight was 14.1% and 7.5% in obese and non-obese families, respectively. Significant associations were observed between child and parent characteristics for overweight, frequency of eating in restaurant, television hours, and hours of physical activity. Child overweight was associated with parental overweight (Odds Ratio [OR] 2.43, 95% CI 0.78, 6.59), low maternal education level (OR 2.22, 95% CI 1.39, 3.55), food restriction (OR 2.68, 95% CI 1.64, 4.29), and television watching >2h/d (OR 1.56, 95% CI 1.17, 2.09), after adjusting for sex, age, family income and kindergarten (for cluster study design). CONCLUSIONS: Overweight prevalence among Chinese preschool children in Beijing is comparable to some European countries. Prevention strategies should include identified lifestyle risk factors.     

High body mass index, asthma and allergy in Swedish schoolchildren participating in the International Study of Asthma and Allergies in Childhood: Phase II

AIM: To assess the relationship between high body mass index (BMI) and asthma and atopic manifestations in 12-y-old children. METHODS: The relationship between high BMI and asthma symptoms was studied in 457 sixth-grade children, with (n = 161) and without (n = 296) current wheeze. High BMI was defined as > or = 75th percentile of gender-specific BMI reference values for Swedish children at 12 y of age; overweight as a subgroup of high BMI was defined as > or = 95th percentile. Children with a BMI < 75th percentile served as controls. Questionnaires were used to assess asthmatic and allergic symptoms, and bronchial hyperresponsiveness was assessed by hypertonic saline provocation tests. RESULTS: Current wheeze was associated with high BMI after adjustment for confounding factors (adjusted OR 1.7, 95% CI 1.0-2.5) and overweight had an even more pronounced effect (adjusted OR 1.9, 95% CI 1.0-3.6). In addition, asthma severity was associated with high BMI, as evaluated by the number of wheezing episodes during the previous 12 mo among the wheezing children (adjusted OR 2.0, 95% CI 1.0-4.0). There was also an association between high BMI and the presence of eczema in wheezing children (adjusted OR 2.2, 95% CI 1.0-4.6). However, high BMI was not significantly associated with hay fever, positive skin prick tests or bronchial hyperresponsiveness. CONCLUSION: The study confirms and extends a previously observed relationship between BMI and the presence of wheezing and asthma.     

Obesity class does not further stratify outcome in overweight and obese pediatric patients after heart transplantation

The effect of obesity stratification on pediatric heart transplant outcomes is unknown. The UNOS database was queried for patients ≥2‐<18 years listed for heart transplant and stratified by BMI: normal (BMI>5%‐≤85 percentile), overweight (BMI=86%‐95 percentile), class 1 (BMI=100%‐120% of 95 percentile), class 2 (BMI=121%‐140% of 95 percentile), and class 3 obesity (BMI>140% of 95 percentile). A total of 5056 individuals were listed for transplant, with 71% normal, 13% overweight, 10% class 1, 4% class 2, and 2% class 3 obesity. Waitlist survival was not different between groups. Post‐transplant survival was decreased in overweight and combined obese groups vs normal, with no further difference between overweight and obese classes. Overweight and obese patients had higher listing status and were more likely to have ventilator, inotrope, and mechanical circulatory support at listing. After transplant, there was an association of overweight‐obese patients with diabetes and rejection requiring hospitalization. Stricter definition of normal weight reveals overweight‐obese status was an independent risk factor for poorer post‐transplant survival, without further effect by stratification of weight class. However, because there is no difference in waitlist survival, this study does not allow the selection of absolute weight‐based criteria regarding transplant listing and suggests the need to look further for modifiable risk factors post‐transplant.     

Eating habits and attitudes of mothers of children with non-organic failure to thrive

The eating habits and attitudes concerning body shape and weight among 26 mothers of children with non-organic failure to thrive (the index group) were studied using the eating disorder examination. They were compared with equivalent data on 26 individually matched women who participated in a large community survey. The index mothers' views of their child's weight and shape were also studied. The principal findings were, firstly, that when compared with the comparison group, mothers of children with non-organic failure to thrive had higher levels of dietary restraint. Secondly, despite their child's low weight, 50% of the index mothers were restricting their child's intake of 'sweet' foods, and a further 30% were restricting foods they considered 'fattening' or 'unhealthy'. These results raise the question of whether maternal eating habits and attitudes have a causal role in the genesis of non-organic failure to thrive. They suggest that careful inquiry about the mothers' eating habits and attitudes is needed when assessing children with non-organic failure to thrive.

Resource utilization and expenditures for overweight and obese children

OBJECTIVES: To compare health care utilization and expenditures for healthy-weight patients, overweight patients, and patients with diagnosed and undiagnosed obesity and to examine factors associated with a diagnosis of obesity. DESIGN: Retrospective study using claims data from a large pediatric integrated delivery system. SETTING: An urban academic children's hospital. PARTICIPANTS: Children aged 5 to 18 years who presented to a primary care clinic for well-child care visits during the calendar years 2002 and 2003 and who were followed up for 12 months. MAIN OUTCOME MEASURES: Diagnosis of obesity, primary care visits, emergency department visits, laboratory use, and health care charges. RESULTS: Of 8404 patients, 57.9% were 10 years or older, 61.2% were African American, and 72.9% were insured by Medicaid. According to the criteria of body mass index (calculated as weight in kilograms divided by the square of height in meters), 17.8% were overweight and 21.9% were obese. Of the obese children, 42.9% had a diagnosis of obesity. Increased laboratory use was found in both children with diagnosed obesity (odds ratio [OR], 5.49; 95% confidence interval [CI], 4.65-6.48) and children with undiagnosed obesity (OR, 2.32; 95% CI, 1.97-2.74), relative to the healthy-weight group. Health care expenditures were significantly higher for children with diagnosed obesity (adjusted mean difference, $172; 95% CI, $138-$206) vs the healthy-weight group. Factors associated with the diagnosis of obesity were age 10 years and older (OR, 2.7; 95% CI, 2.0-3.4), female sex (OR, 1.5; 95% CI, 1.2-1.8), and having Medicaid (OR, 1.6; 95% CI, 1.1-2.3). CONCLUSIONS: Increased health care utilization and charges reported in obese adults are also present in obese children. Most children with obesity had not been diagnosed as having obesity in this administrative data set.     

Maternal perception of excess weight in children: a survey conducted by paediatricians in the province of Milan

OBJECTIVE: To establish whether maternal perception of a child's body weight (BW) and food intake is related to the level of maternal education. STUDY DESIGN: Height and BW of 569 mother/child couples were measured, and mothers received a questionnaire regarding their perception of their own weight and their child's BW and food intake. RESULTS: Twenty-nine percent of mothers and 35% of children were overweight or obese. Only 10% of the mothers underestimated their own weight, while 37% overestimated it. In contrast, 28% of mothers underestimated their child's BW, while 9% overestimated it. Higher maternal instruction level was significantly associated to a lower weight class in both mothers and children, and to a correct perception of the child's weight. Fifty-seven per cent of the mothers who perceived their child to be overweight or obese were not concerned. Forty-four per cent of the mothers with overweight or obese children believed that their child was eating correctly. CONCLUSIONS: A better understanding of how mothers perceive the problem of excess weight in their children is relevant to the success of preventive interventions in childhood obesity.     

Connections between parental eating attitudes and children's meagre eating: questionnaire findings

This study investigated whether young children's problematic, meagre eating is associated with the eating habits and attitudes of the parents. The subjects, 397 children, their mothers (n = 397) and fathers (n = 375) participated in a prospective atherosclerosis risk-factor intervention trial. The parents evaluated their own eating behaviour in questionnaires when their child was 13 mo old. The children's eating problems were recorded by the mothers when the child was 13 mo old, and by both parents when the child was 5 y old. At both ages, the weight and height of the children were measured. Problematic or maladaptive eating habits of the children were found to be connected to those of their parents. The mother's poor ability to enjoy eating, high tendency to snack and low tendency to eat only when hungry, as well as the father's difficulty in maintaining ideal weight significantly predicted persistent problems of meagre eating in their children. CONCLUSION: The study suggests that the eating habits and attitudes of parents may be reflected in the eating behaviour of young children.     

Prepregnancy Maternal Weight and Body Mass Index of Children with and without Congenital Heart Disease

Objective: Congenital heart diseases are among the most frequent major congenital anomalies. One of the suspected reasons for congenital heart defects is overweight and obesity of mother during prepregnancy and pregnancy. We studied the relationship between maternal overweight and obesity and the risk of congenital anomaly. Methods: All of children with congenital heart defect (164 infants with major nonsyndromic heart disease) referred to our pediatric cardiology clinic or admitted to our ward during 2011-2012 were included in this study. Controls were 158 live-born infants without any major malformations and their mothers. Mothers of these infants were studied for weight, height and body mass index (BMI). Findings : The most frequent congenital heart disease was ventricular septal defect (39%), patent ductus arteriosus (11%), complete atrioventricular septal defect (10%), pulmonary stenosis (9.1%), and atrial septal defect (8.5%). There was no significant difference between maternal age (P=0.1), weight (P=0.8) and height (P=0.3) in the two groups. The mothers had not significantly higher BMI than that of the control mothers. Compared with underweight (BMI <18.5) and normal weight women (OR: 1.24, 95%CI: 0.40-3.89), overweight (OR: 0.98, 95%CI: 0.31-3.10) and obese women (OR: 1.16, 95%CI: 0.34-4.00) were not more likely to have an infant with a congenital heart defect. Conclusion: This study suggests that there may not be a relation between maternal BMI and having a child with congenital heart defect.Key Words: Congenital Heart Defects; Maternal Obesity; Maternal Overweight     

Restrained eating in overweight children: does eating style run in families?

Overweight children show abnormalities in eating style, such as restrained eating and tendency toward overeating (comprising both emotional and external eating). Family surroundings play a major role in developing eating behaviors in children. We tested whether restrained eating and tendency toward overeating predicted the amount of food intake in 41 overweight children (23 girls and 18 boys) and their parents (40 mothers and 11 fathers) after receiving a preload. We further investigated with questionnaires whether there were associations between the parents' and their children's eating behavior and whether mothers' food intake predicted the amount of food consumed by children in an experimental trial. We found that neither children with restrained eating nor their mothers ate more after a preload, but children with a high tendency toward overeating ate somewhat more after receiving a preload. Further analyses showed that children's food intake in the preload paradigm was predicted by mothers' food intake. Our findings point to a familial transmission of eating styles: children eat as their primary caregivers do, even when the caregivers are not present in the laboratory.     

Obesity and lipid profiles in children and adolescents

Childhood obesity is associated with unfavorable lipid profile, suggesting that obese children should be screened for hypercholesterolemia. However, the prevalence of hypercholesterolemia in childhood obesity, and the effect of the degree of obesity on lipid profile, are unknown. Eighty-nine obese children and adolescents (BMI >85%, mean age 10.4 +/- 2.5 years) and 53 non-obese control children matched for age, gender and pubertal stage participated in the study. Early morning blood samples for serum lipids were collected in all children after a 12-h fast. Mean serum cholesterol and triglycerides (TG) levels were significantly higher (p <0.05) among the obese children (cholesterol: 175.2 +/- 31.4 vs 143.3 +/- 24.3 mg/dl; TG: 122.8 +/- 69.7 vs 94.3 +/- 37.8 mg/dl in obese and control children, respectively). Among the obese children, 52% had elevated serum cholesterol levels (>170 mg/dl) compared to 16% in the controls. The degree of obesity (BMI 85-95% vs BMI >95%) had no effect on serum lipids. Unfavorable lipid levels were relatively common among obese children, suggesting that obesity should be considered a risk factor for hypercholesterolemia, and that screening obese children for hypercholesterolemia should be considered.     

Obesity and type 2 diabetes mellitus: a population-based study of adolescents

A cross-sectional, population-based study was conducted on 1,647 Turkish adolescents to determine the prevalence of obesity, impaired fasting glucose (IFG) and type 2 diabetes mellitus (DM2), and to determine whether the recent increase in DM2 prevalence in some countries is applicable to this population. Information was gathered through a questionnaire. All children were screened with physical examination and fasting plasma glucose. 10.7% of adolescents were overweight (BMI 85-95th percentile) and 3.6% were obese (BMI > or =95th percentile). Mean BMI was 20.25 +/- 3.31 kg/m2 with maximum BMI 35.88 kg/m2. No child was diagnosed with DM2; 1.96% had IFG (110-126 mg/dl). No significant relationship was found between IFG and obesity, socio-economic status (SES) or family history of DM. The risk of obesity was increased among children with family history of DM or obesity, and among those who had low physical activity and were of high SES level. This analysis represents the population-based data upon which future studies will be based.     

Sex disparity and perception of obesity/overweight by parents and grandparents

OBJECTIVE:

To explore the factors associated with the sex disparity showing a greater prevalence of obesity/overweight in boys compared with girls in Chinese school children.

METHODS:

Sampled students and their parents were asked to complete a questionnaire. Perceptions of weight status by the parents, grandparents and children themselves were collected. A logistic regression analysis was used.

RESULTS:

The sampled students included 327 obese/overweight students and 1078 students with normal body mass index (BMI). The crude OR of obesity/overweight for boys compared with girls was 1.57 (95% CI 1.22 to 2.01). The increased risk of childhood obesity/overweight for boys remained after adjustment for prenatal and infant factors, daily habits and family situation, but disappeared after adjustment for perception of weight status (OR 1.27 [95% CI 0.93 to 1.67]). There were differences in underestimation of children’s weight status between boys and girls by their parents and grandparents (OR 1.33 [95% CI 1.08 to 1.64] and OR 1.42 [95% CI 1.15 to 1.75], respectively).

CONCLUSIONS:

Misconceptions about a child’s weight status were prevalent among parents and grandparents, and boys’ weight status was more frequently underestimated than girls. The disparity of underestimating weight according to sex may partially contribute to the difference in the prevalence of obesity/overweight between boys and girls among Chinese school children.     

Maternal prepregnancy body mass index in relation to Hispanic preschooler overweight/obesity

The aim of the current study was to examine the role of maternal prepregnancy body mass index (BMI) on overweight/obesity among US Hispanic children ages 2 and 4 years old. We used US nationally representative data from preschoolers enrolled in the Early Childhood Longitudinal Study-Birth Cohort study. The findings revealed that a significantly higher percent (41.6%) of Hispanic mothers were overweight/obese prior to pregnancy compared to white mothers (34.8%). At 2 years of age, 38.3% of the children born to Hispanic mothers were overweight/obese compared to 29.4% of children born to white mothers. By the age of 4, overweight/obesity increased significantly for both racial/ethnic groups with preschoolers whose mothers were Hispanic being more likely to be overweight/obese (44.6%) compared to children whose mothers were white (34.2%). Further, preschoolers born to overweight/obese Hispanic mothers were more than twice as likely [odds ratio = 2.74 (95% confidence interval (CI) 1.60, 4.69)] to be overweight/obese than those born to Hispanic mothers of normal prepregnancy BMI. Preschoolers born to overweight/obese white mothers were approximately 1.4 (95% CI 1.05, 1.93) times more likely to be overweight/obese in comparison to those born to mothers with a normal prepregnancy BMI. Maternal prepregnancy weight is potentially a modifiable risk factor for preschooler overweight/obesity. Study findings support the design of early and targeted interventions to reduce this risk to the long-term health of Hispanic maternal and child dyads.
